  • Chemical Name: isoniazid (INH) (eye-so-NYE-a-zid)
  • Usage in MS: Tremors
  • Generic Available: Yes

Description

Isoniazid is used to prevent or treat tuberculosis. It may also be used for other problems as determined by your physician. In MS, it is used for certain types of tremor.

Proper Usage

If isoniazid upsets your stomach it should be taken with food. Antacids may help but those containing aluminum should be avoided. Check the label.

Tell your physician if you are on a low-sodium, low-sugar, or any other special diet before taking isoniazid.

Precautions

Your doctor may want you to take pyridoxine (Vitamin B6) every day to help avoid side effects. If pyridoxine is needed, it must be taken every day; do not skip doses.

Isoniazid has not been shown to cause birth defects in humans or animals. Studies have shown an increased risk of fetal death in animals.

Isoniazid passes into breast milk.

Possible Side Effects

Side effects that usually go away as your body adjusts to the medication and do not require medical attention unless they persist or are bothersome: nervousness; restlessness; sleep difficulties; dizziness; rapid heartbeat; flushing; headache; sweating; nausea; trembling; weakness*; pink or red saliva.

Side effects that should be reported to your physician as soon as possible: chest pain; irregular heartbeat.

*Since it may be difficult to distinguish between certain common symptoms of MS and some side effects of isoniazid, be sure to consult your health care professional if an abrupt change of this type occurs.
